To all whom it may concern Be it known that I, CHARLns J. PILLIOD, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have made an Invention Apportaining to Adapter Means for Furnace Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to ,make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of thisspecification.

This invention relates to fire doors for locomotives, or the like, and particularly to an adapter ring for use in connection therewith.

The object of my invention is the provision in connection with a stoke hole of a locomotive, furnace, or the like, and a fire door therefor, of means for adapting the fire door for use in connection with stoke holes of different shapes and styles, and which also serves as a protecting; means for the wall of a stoke hole and particularly for that part thereof with which the shovel of a Stoker is likely to engage when fuel is being); shoveled into the furnace.

A further object of the invention is the provision of an adapter or contour ring of the class described, which, when it becomes worn or broken, may be easily and quickly replaced without necessitating the replacement of the entire door frame, as is now commonly the case.

The invention is fully described. in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the; accompanying drawings, in which, l Figure 1 is a front elevation of a door frame and adapter ring embodying the invention in assembled form and with the doors open and parts broken away Fig. is a central vertical section. of my inns-n tion applied to a locomotive with the associated doors closed. Fig. 3 is a front face view of an adapter ring embodying; the invention. .Fig. 4.. is an enlarged section thereof on the line l-4t in Fig. 3 together with a fragmentary section of a casing wall. Fig. 5 is an enlarged section on the line 5--5 in Fig. 3, and Figs. 6 and 7 are enguide for a pair of oppositely sliding doors l-l, which are operated by any suitable mechanism. The frame is secured to the furnace casing by bolts 5, or in any other suitable manner, and has an opening 6 therein in register with the stoke hole 2 and substantially, but not necessarily, of the same size and shape as the stoke hole.

The frame 3 is outwardly spaced, particularly at its inner marginal edge portion from the casing; 1, and an adapter ring; 7 is disposed within. the space and. clampedby the frame to the casing 1 at the marginal edge of the opening 2. The adapter ring 7 is held rigidly centered or positioned within the frame 3 by a series of lugs 8, which project inwardly from the inner side of the frame 3 in outwardly spaced relation to the opening 6 therein and in position to coact with the outer peripheral side of the adapter ring at spaced distances therearound, as shown. Y n

The adapter ring 7 is of U-form in crosssection to form the loop or cross-portion 9 and the inner and outer spaced legs or flanges 10 and 11, with respect to the center of the ring,projecting inwardly therefrom. The loop portion 9 forms the outer face of the ring andis adapted to bear flatwise against the inner side of the frame 3, at the inner marginal edge of the opening 6 thereimand is of a shape and size adapted to conforinsubstantially to the shape and size of the opening 6. The outerleg or flange 11 of the ring preferably projects inwardly from the looped portion 9 at substantially a right angle thereto to hear at its free end against the casing 1 at the marginal edge of its opening, substantially as illustrated. This leg of the ring is drawn rigidly to the casing by the inward clamping action of the frame 3. In the present instance the leg 11 is shown as provided at
